Description
Flash Key Register Error Detect
Checks the FKEY value (H'5A) before erasure starts,
and returns the result.
0: FKEY setting is normal (H'5A)
1: FKEY setting is abnormal (value other than H'5A)
Erase Block Select Error Detect
Checks whether the specified erase block number is in
the block range of the user MAT, and returns the result.
0: Setting of erase block number is normal
1: Setting of erase block number is abnormal
Unused
These bits return 0.
Success/Fail
Indicates the erasure result.
0: Erasure has ended normally (no error)
1: Erasure has ended abnormally (error occurs)
